Background GrainOut is a subsidiary of Benzoil that specialises in food and beverage by-products. Bentonite is a by-product from the edible oil manufacturing process and one of GrainOut’s products. It is predominantly used in animal feed as a pH buffer to neutralise the effect of lactic acid build up (acidosis) from cereal feed, however

Background Whey is a by-product of the dairy industry with its main component being whey protein.  Benzoil’s GrainOut business unit specialises in the niche area of value added product creation.  GrainOut has identified alternate opportunities to reusing whey protein as a liquid animal feed in Australia. Whey is the liquid by-product remaining during cheese

GrainOut, a niche business unit of Benzoil, specialises in food by-product removal and value added product generation. We work with food manufacturers to ensure that opportunities for effectively repurposing food by-product waste are realised.  Many opportunities exist for our food manufacturing clients to maximise value and sustainability of their by-product waste.  Food by-products have levels

KNAN, KNAF, ONAN, ONAF – what do they mean?  Here’s how to unlock the cooling class code for liquid filled transformers. The ANSI/IEE Standard C57.12.00 defines a 4 character code to describe the cooling attributes of the transformer.  The first letter refers to the main cooling medium (i.e. in contact with the windings).  Decode as

Whether the insulating fluid be mineral oil, vegetable oil (esters) or synthetic, we can supply the product to match the need. Just as oils vary in design, transformers themselves are abundantly different – many with similar properties and some quite specialised and unique.  Here are some of the electrical transformers for which can supply dielectric

Transformer oil pricing in the Australian market has been relatively stable for some years, but recently with oil prices more widely increasing so has pricing for transformer oil.  Factors that influence the price we pay for any oil product in Australia are the Australian currency, the barrel price for oil, market expectations, and supply and

The quality or performance of electrical insulating oil is dictated by its chemical structure.  Chemical structure determines the consistency of its viscosity performance, it resistance to oxidation (longevity of performance) and its compatibility with other materials. In addition to chemistry, the purity (moisture content and impurities) of the oil also influences many of the oil

Naphthenic versus paraffinic oils – which is better? The answer is not so straightforward because the application will drive the choice of oil. In the case of transformers there is a lot more historical data and knowledge on naphthenics than on paraffinics, and naphthenic oil has traditionally been considered the gold standard. However paraffinic oil

Mineral oil is by far the most abundant transformer fluid in use in Australia.  There are however other options, which do have their place in specific transformer applications including chlorinated hydrocarbons (e.g. PCB which is banned), high molecular weight hydrocarbons, biofluids, esters, and silicone fluids. Silicone fluids or more correctly polydimethylsiloxane (PDMS) are a type
